Program E-load
Select this mode to access the electronic-load function. Electronic load can be used as the load for
battery discharge, switching power supply or charger. It can be easily set to these discharge modes:
constant-current, constant-voltage, constant-resistance, and constant-power. With this function, the
discharge performance of the battery can be visually measured (the discharge voltage can be up to
10A), the service duration of the battery working in the constant-power (for example, by
simulating the power consumption of 10W of an electrical appliance) can be measured, and the
maximum output current of the battery working in the constant-voltage mode can be measured.
Therefore, this function very helpful.
After the electronic-load function is accessed, the interface is shown as below.
Constant voltage mode The tester is On.
Setting current..... Output voltage
Cut-off voltage.... Output current
The first line indicates that the tester is working in the electronic-load mode.
The second line indicates that the current electronic-load mode is constant-current.
This tester supports four electronic-load modes:
1.
CC
(constant-current):
The
tester
automatically
regulates
the
operating
current
to
make
it
constant.
2.
CV
(constant-voltage):
The
tester
automatically
regulates
the
operating
voltage
to
make
it
constant.
3.
CR
(constant-resistance):
The
tester
automatically
regulates
the
operating
current
to
ensure
that the ratio of voltage to current is constant, and enables the electronic-load to simulate a
fixed resistor with the resistance set.
4.
CP
(constant-power):
The
tester
automatically
regulates
the
operating
current
to
ensure
that
the product of current and voltage, namely power, to be constant.
